One of the analyzed miRNAs in the present paper is miR-155 which was shown to inhibit the suppressor of cytokine signaling (SOCS1)—a negative regulator of the Janus kinase/signal transducers and activators of transcription (JAK/STAT signaling); thus, elevating the expression of miR-155 could enhance inflammation in the intestine of IBD patients by immune system perturbation [25, 26]. The gene discussed is SOCS1; the disease is inflammatory bowel disease.
